.SH DESCRIPTION
.sp
.LP
The \fBdelch()\fR and \fBwdelch()\fR functions delete the character at  the
current cursor position from \fBstdscr\fR and \fIwin\fR, respectively.  All
remaining characters after cursor through to the end of the line are shifted
one character towards the start of the line. The last character on the line
becomes a space; characters on other lines are  not affected.
.sp
.LP
The \fBmvdelch()\fR and \fBmvwdelch()\fR functions delete the character at  the
position specified by the \fIx\fR and \fIy\fR parameters; the former  deletes
the character from \fBstdscr\fR; the latter from \fIwin\fR.
